EDWARD TIIEIsEN, or COLOGNE, GERMANY APPARATUS 'FOR CONDENSNG ANDCOOLING PURPOSES.

SPECIFICATION forming part of Letters Patent No. 443,015, dated December16, 1890.

Application led January 3, 1888. Serial No. 259,694. (No model.)

T0 tzr/ZZ whom t may concern:

Be it known that I, EDWARD TIIEIsEN, of Cologne, in the Kingdom ofPrussia, German Empire, have invented an Improvement in Apparatus forOondensing and Cooling Purposes, of which the following is aspecification.

This invention is a modification of the devices shown in Letters PatentNo. 363,091, granted to me May 17, 1887; and such invention consists inthe combination of devices hereinafter set forth.

In the drawings, Figure l is a vertical longitudinal section of theapparatus. Fig. 2 is a cross-section at the line and Fig. is across-section at the line y y.

The vessel u is of suitable size and shape, and it is to contain thecooling-liquid. In the lower part of such vessel there are chambers orpassages, through which vapors or gases to be cooled or condensed arepassed. I have represented ranges of pipes opening at their ends intothe respective chambers 2 and The fluids or gases to be cooled aresupplied to the chamber 2 and pass through the pipes e' and away by thechamber The heat passing off from the pipes i warmsthe liquid in thevessel c, and in order to cool such liquid and maintain the same at anormal or nearly normal temperature I make use ot' concentric truncatedcones S, and the same are connected to and revolved byacentral shaft 3,supported in suitable bearings 4t and driven by a band to the pulleys 5or otherwise, and a current ot' air is allowed to pass into and throughthe truncated cones, and such air is supplied by the hood 6 at one endand taken ot'f by the flue 7 at the other end, preferably to a chimney,so as tomaintain a rapid circulation of air through the truncated cones.

In Fig. 1 a stationaryT semicircular case 9 is represented at the end ofthe concentric truncated cones and connected with the hood G and asimilar scmicircular case 10 at the other end of the truncated conesconnected with the Hue 7'. Itis now to be understood that as thetruncated cones S revolve the liquid in the vessel d is agitated andcaused to circulate through the truncated cones, and these cones and theliquid adhering` to their surfaces are cooled by the passing current ofair, so as to maintain the cones and the liquid at a normal temperature,or nearly so, in order that the liquid in the vessel ct may act withuniformity in cooling the fluids within the pipes or chambers in thelower part of said vessel n.

I claim as my invention- The combination, with avessel for containingthe cooling-liquid, of pipes or hollow bodies within such cooling-liquidand through which the liuid to be cooled passes, and a group ofconcentric truncated cones and a shaft for supporting and revolving thesame in the cool- 4 ing-liquid, and means for directing a current of airthrough between the hollow concentric truncated cones, substantially asset forth.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribingr witnesses.

EDWARD THEISEN.
